Garage door Sensor

One of the sensors on my garage door opener wires came out. I ordered a new one and they sent me a pair. I replaced the broken one and have a solid green light but when i press the opener it still justs starts and then stops. do i have to replace both of them together. Also when i put my hand in the way of the sensor they both just stay green whats wrong here?

It is important to have your garage door working properly so you can access you belongings or to keep your belongings safe. While your waiting on an expert response you can visit the SearsHomeServices website to schedule service. I have provided the link below. Good luck!

The door safety sensors come as a pair because one is a sender and the other is a receiver. I suspect you have 2 sending sensors on your door now. I suggest replacing both door sensors and be sure they are aligned. I think this will solve your problem.
